PORTABLE GAS-LIGHTING OUTFIT.

Specification of Letters Patent.

Application filed January 22, 1918. Serial No. 213,121.

T 0 all whom it may concern:

Be it known that I, CHARLES E. VER- HUNCE', a citizen of the UnitedStates, and a resident of Chicago, in the county of Cook and Stateoflllinois, have invented certain new and useful Improvements inPortable Gas-Lighting Outfits, of which the following is a full, clearand exact description.

The invention relates to portable gas lighting outfits.

One object of the invention s to provide an improved portable gas lampwhich is adapted for service in a tent or other struc ture. V Inlighting outfits of this character, it is desirable to provide a lampwhich may be supported over head without danger of burning the tent orstructure in which the outfit is installed. To meet this requ1re- 'ment,the invention includes a portable gas lamp which is organized andsupported so as to overcome any danger of a conflagration. I

In attaining this" object, the lamp is provided with one or more supplyconnections at one side thereof, as distinguished from the usualcentralcombined supply pipe and support. This provision makes itpossible to use flexible'tubing to supply gas to the lamp and to keepthe tubing out of the upward path of the heat or products of combustionfrom the burner; In conjunction with the side gas connection, a flexible metallic support, such as a chain which is noninflammable, isutilized to support the lamp in desired position from the ridge pole ofthe tent or other support of the structure in which the lamp isinstalled. A further object of the invention is to provide an improvedconstruction of gas lamp in which there is no flame 1n the cen tralportion of the lamp, so that there wlll be a current of air flowingupwardly which serves to quickly cool the products of combustion, theburners being circumferen-tially disposed within and around thereflector.

Another object of the invention is to providean improved reflector andsupport for a portable gas lamp which are slidably connected so that thesupport may he slipped into the reflector for convenience 111 packingtheoutfit. It will be understood that it is the desideratum in lightingoutfits of this character to pack the parts in a small areaforconvenience in transportation.

Lastly, the invention designs to provide a portable gas lamp which issimple in con- 1 trated as installed in a hospital tent a andcomprisesaportable gas tank 6 and a flexible tube 0 which is suitablyconnectedtothe tank and controlled by a suitable valve as wellunderstood in the art, to supply gas to a portable lampsuspended fromthe top of the tent or structure.

The improved lamp comprises a conoidal reflector 7. Around the lowermargin of the reflector, there isdispo'sed a hollow ring 8, to which ametallic nipple 9 is connected by means of a valve 10, to supply gas tothe ring 8 from the flexible tube 0. Ring 8 is connected to the lowermargin of the reflector 7 by slotted lugs or plates 13 and thumb-screws14:. For convenience in packing and assembling. the tube 0 is detachablyconnected to the nipple 9 by a coupling 11. A. series of burners 12extend inwardly and slightly upwardly from the inside of the hollowring'8 and below the lower margin of the reflector. The reflector ispreferably formed ofsheet metal and has an opening 7 in its top, themetal being reverted as at 15 to stiffenthe upper portion of thereflector. A hood 16 is slidably mounted in the top ottlhe reflector andcomprises a cylindrical metal body 16 whichis provided with outwardlyextending struckup tongues 17 which serve as stops upon which thereflector rests and by which it is supported from the hood and a bowl ortop-shade 18 which is secured in fixed andspaced relation to the top ofthe body 16 by lugs 19 which are riveted to the cowl and said body. Thebody 16 is also provided with outlet openings 20 which are formed bybending tongues 21 inwardly. v The products of combustion escape throughthese openings 20 and the Patented May 24, 1921. p

space between the body 16 and cowl 18. The tongues 21 and cowl l8 serveto deflect the heat laterally so there will be no strong upward draftthat will endanger the structure in which the lamp is installed. Ametallic chain 22 is secured to an eye 23 which is socured in the cowll8 and is adapted to be looped around the ridge pole of a tent or anyother convenient support and is provided with a hook 24 adapted to passinto the eye 23 to support the lamp in desired overiead position. v

In some instances, it is desirable to supply an additional lamp orburner from the supply hose 0. For example, a small burner to illuminatethe entrance to the tent and for this purpose a metallic nipple 25 issecured to thehollow ring 8 diametrically opposite to the nipple 9 and asemi-circular supply pipe is connected to these nipples to conduct gasto nipple '25 from nipple 9. An auxiliary flexible tube section cl isconnected to the nipple 25 by a detachable coupling26 and thisflexibletube is suitably connected to the auxiliary'burner 6. The supplyof gas through the tube (Z is controlled by a valve 6 at the burner e.The flexible tubes are supported beneath the ridge-pole by .and bedeflected laterally to breakup any strong draft which might causeignition of the structure in which the lamp is installed or of theflexible tubing.

The invention thus exemplifies a gas burner in which provision is madefor a central current of cool air tocool the prod nets of combustion andprevent a strong upward draft to apoint above the lamp.

Also one in which shadows are avoided.

In a portable lighting outfit, it is desirable that the parts of thelamp should be susceptible of being packed into a small container, andthe slidable connection between the body 16 and reflector 7 exemplifiesa portable gas lamp by which the hood may he slipped downwardly into thereflector, as indicated by'dotted lines in Fig. 5. As a result, thisconstruction can be packed in a cylindrical box orcontainerapproximately the height of the reflector, in lieu of the 7combined eflective'height of the hood and reflector; The coil offlexible tubing may .be disposed-, in the box around the upper portionof the reflector.

The invention is not to be understood as restricted to the details setforth, since these may be modified within thescope' of the appendedclaims, without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is:

1.111 a portable gas lighting outfit, the combination of a reflectorhaving an open bottom, one ormore, gas burners adjacent the bottom ofthe reflector, a gas supplying connection "for the burners, and a hoodsliding a perforated cylindrical body and a cowl.

3. In a portable gas lighting outfit, the combination of a reflectorhaving an open bottom, one or more burners adjacent the bottom of thereflector, a gas supplying connection for the burners, disposed at oneside of the reflector, a flexible tube connected to said connection, ahoodslidablyconnected to the reflector and adapted to be folded into thereflector, and comprising a cowl, a flexible-metallic suspension deviceconnected to said cowl, and supporting stopmeans between the hood andthereflector;

4. In a portable gas lighting outfit, the combination of a reflector,one or more burners adjacent the bottom of therefleetor, a gas supplyingconnection for the burners, and a hood slidably connected to thereflector and adapted to be folded into the reflector, saidhoodcomprising a hollow body being formed with openings and-struck-uptongues. r

5.- Ina portable gas lighting outfit, the combination of a reflector,one or more burners adjacent the bottom of the reflector, a gassupplying connection for the burners, and a hood slidably connected tothe reflector and adapted to befolded into the reflector, said hoodcomprising a hollow body,

I 6. In a portable gas lighting outfit, the combination of an annularconoidal reflector, a plurality of gas burners adjacent the bottom ofthe reflector, a hollow ring to V which the burners are connected, anipple at one side of the ring, a flexible tube adapted .to be connectedto said nipple, a'hood connected to the reflector, comprising acowl,

and a perforated body, a non-inflammable flexlble suspension device forthe hood and adapted to support the lamp, and a supporting connectionbetween the reflector and the hood.

7. In a portable gas lighting outfit, the combination of an annularconoidal reflector, a plurality of gas burners adjacent the bottom ofthe reflector, a hollow ring to which the burners are connected, anipple at one side of the ring, a flexible tube adapted to be connectedto said nipple a hood slid- 10 ably connected to the reflector,comprising a cowl and a perforated body, a non-inflam-- lnable flexiblesuspension device for the hood and adapted to support the lamp, and asupporting connection between the reflector 15 and the hood.
